This awesome viaduct in South England

From Reddit: It's 178 years old! It cost the equivalent of around £3m to build back then, with 11,000,000 bricks brought up the Ouse river from the Netherlands and topped with French limestone. Since then it's had many times the original build cost spent on maintenance, it was originally designed to have a 120 year lifetime. But now that it's listed (and forms a key part of the London-to-Brighton mainline) it's hopefully here to stay for a lot longer still. Here's a view of it from another perspective: https://i.imgur.com/qk7KCT3.jpg
